Hey -
When your tutorial is checked and added to the database, it will be new, the new tutorials are the ones that have just been checked and approved, by hand, 1 by 1, by Faken [Owner]
There are hundreds and hundreds of tutorials added to the site every week, and faken has to check each and every one and approve them.
Heres a couple reasons why yours aren't up yet:
They haven't been approved
They are still in the queue
Just be patient, tutorials can take some time to get approved because it isn't an automatic approval system, they are all looked over by Faken. So some tutorials will appear on the site later than sooner.
Hope this is of some kind of help!
